Package javax.enterprise.inject.spi Description
The portable extension integration SPI.
A portable extension may integrate with the container by:
- Providing its own beans, interceptors and decorators to the container
- Injecting dependencies into its own objects using the dependency injection service
- Providing a context implementation for a custom scope
- Augmenting or overriding the annotation-based metadata with metadata from some other source
The BeanManager object
Portable extensions sometimes interact directly with the container
via programmatic API call. The interface
BeanManager provides operations
for obtaining contextual references for beans, along with many other
operations of use to portable extensions.
Container lifecycle events
During the application initialization process, the container fires a series of events, allowing portable extensions to integrate with the container initialization process. Observer methods of these events must belong to extensions declared in META-INF/services.
Lifecycle events include
BeforeBeanDiscovery,
AfterBeanDiscovery,
AfterDeploymentValidation and
BeforeShutdown.
Interfaces representing enabled beans
The interfaces
Bean,
Decorator,
Interceptor and
ObserverMethod
define everything the container needs to manage instances of
a bean, interceptor, decorator or observer method.
An instance of Bean exists for every
enabled bean. A portable
extension may add support for new kinds of beans by implementing
Bean, observing the event
AfterBeanDiscovery event
registering beans with the container. An instance of
ObserverMethod exists for every
observer method of every
enabled bean. A portable extension may add observers by implementing
ObserverMethod and
registering an instance with the container.
A portable extension may be notified of the existence of an
enabled bean by observing the container lifecycle event type
ProcessBean or one of its
subtypes,
or of the existence of an observer method of an enabled bean by
observing the event type
ProcessObserverMethod.
Alternate metadata sources
A portable extension may provide an alternative metadata source, such as configuration by XML.
Annotated
and its subtypes allow a portable extension to specify
metadata that overrides the annotations that exist on a
bean class. The portable extension is responsible for
implementing the interfaces, thereby exposing the metadata
to the container. The container must use the operations of
Annotated and its subinterfaces to discover program
element types and annotations, instead of directly calling the
Java Reflection API.
A portable extension provides its metadata to the
container by observing the event
ProcessAnnotatedType and
wrapping the AnnotatedType.
Producer and InjectionTarget
Producer and
InjectionTarget abstract the
basic lifecycle of (contextual or non-contextual) container managed
objects, including instantiation and destruction, dependency injection
and lifecycle callbacks.
An instance of InjectionTarget
may be
obtained from the BeanManager,
allowing a portable extension to request these container services for
objects under the control of the portable extension.
Furthermore, a portable extension may replace the implementation
of InjectionTarget or
Producer used by the container
with its own implementation by observing the events
ProcessInjectionTarget or
ProcessProducer.
